While hardly surprised by the Italian's dismissal on Monday, Tiatto - an ex-City captain who made 158 appearances in for the club over a six-year stint - expressed doubts over the thinking behind the decision.

"I think it's been on the cards for a while, even though it's going to bring a bit more instability to the club again," the now-retired former Australia international told Goal.com.

"The next coach that comes in is going to bring another set of players in, and then you get the merry-go-round of having a very big squad and a lot of unhappy players.

"So I'm not sure if it may have been the right decision. I know it was disappointing they lost against Wigan on the weekend in the FA Cup final, but I think they're going to go the same way Chelsea did at one stage, with just a circus of coaches and players coming in and going out."

Tiatto agreed the Premier League club had perhaps passed up the opportunity to capitalise on the absence of Sir Alex Ferguson at city rivals and 2012-13 champions Manchester United.

The former Brisbane Roar hardman cited the Scot's long and successful reign at Old Trafford as an example for City to consider.

"I think stability and having a coach there for a long period would have been a better solution for the club," Tiatto said.

"But they've got endless amounts of money, so they're going to try and buy themselves another title by the looks of it."

Even with Mancini still at the club, Malaga head coach Manuel Pellegrini had been heavily linked with the post.

Tiatto said he or former Chelsea coach Carlo Ancelotti - fresh from his Ligue 1 win with Paris Saint-Germain - would have the strong personality required to lead City.

"I think [Carlo Ancelotti] would be a good coach to come in. He can take over a team with so many egos and so many players. He could definitely be a good choice... they might jump in for him even though there has been other speculation as well.

"There was rumours that [Pellegrini] was going to get the job as well. So I think between those two - they're two quality coaches that have been around the traps."
